For me, I never really stopped collecting physical media, particularly CDs. I've been pleasantly surprised to see it make a comeback. I've started collecting cassettes now, too, because I own a couple vehicles old enough that the stock radio has a cassette player.
For command line you won't go wrong with abcde ("A Better CD Encoder") or cdparanoia if you don't need all the bells and whistles. For GUI take a look at asunder.
